Also: I've looked into deduplicating code between the various tun, tap and packet socket code as well. In general it's a good idea. The main counter arguments is that such a break in continuity also breaks backporting fixes to stable. So the benefit must outweight that cost. In this case, the benefits in terms of LoC are rather modest. Not sure it's worth it. Even more importantly: are the two code paths that you deduplicate exactly identical? Often in the past the two subtly diverged over time, e.g., due to new features added only to one of the two. If so, call out any behavioral changes to either as a result of deduplicating explicitly.
